Application led May 10, 1911. Serial No. 626,177.

To all whom t may concern Be it known that I, EFFINGHAM .LAUa RENCE POLLARD, a citizen of the United States, and resident of the town of Dobbs Ferry, county of Westchester, and State of New York, have invented certain new and useful Improvements in Drinking-Fountains, of which the following is a specification.

This fountain is intended as a thoroughly hygienic drinking fountain, and although of the class sometimes seen in parks, and play grounds, it is nevertheless a decided improvement over the commoner types as it has such advantages and rearrangement of parts as to make it perform its duties with greater satisfaction. j

This fountain is constructed in view of cleanliness and for that reason the numerous mouth pieces of glass, porcelain, or crockery are always washed by a ruiming stream, which while thoroughly washing the parts does not necessarily waste a great quantity of water, as means are provided for increasing the flow when it is required, the washing flow may be very small.

Advantages of the construction and arrangement of the parts, as well as the material of which they are made will appear as the specification progresses, though the advantages derived from the filter, its construction and arrangement are readily un-v derstood.

The following is what I consider the best means of carrying out this invention.

The accompanying drawings form a part of this specification, in which:

Figure 1 sho-ws in side elevation, a drinking fountain constructed according to my specification. In this iigure some of the interior parts are shown in dotted lines. Fig. 2 shows on a larger scale, the filter and passages adjacent thereto. This view is in central vertical section, as are the remaining views. Fig. 3 shows the mouth piece and controlling valve therefor and the parts adjacent thereto. Fig. 4l shows a modified construction of the top of the globe. Fig. 5 shows the central portion of the globe and the means for connecting the outlet nipple. Fig. 6 shows a mouth piece having a duplex outlet. This figure is in side elevation.

Fig. 7 shows a mouth piece provided with a cap or cover to be used in conjunction therewith. This iigure is also in side elevation.

Similar reference numerals indicate like parts in all the figures where they appear.

Referring to Fig. 1, the base is indicated at 1. I construct the base of cast iron, and it is my intention to carefully enamel this as well as all of the other metallic parts eX- cept where two metallic parts rub against each other or where there is fear of damage to the enamel, either in wear or in operation. The base indicated by 1 comprises the pedestal 2, having the flange and ornamented stylobate 3, and a bowl 4, all cast integral. The column 2, is hollow and may be provided with the door 5 for easy access to the interior. `Supported in the center of the `bowl 1, is the short nipple 6, and secured to the upper end of the nipple is a member 7, which while providing liberal passages for the easy flow of water, also serves as a retainer for the filter. An inlet pipe S, connects the nipple 6 with a convenient source of water supply under pressure, and a valve 9, in the pipe 8, and arranged within the pedestal or column 2, serves to control the How of water.

Now referring to Fig. 2, I will detail the construction of the filter and the parts adjacent thereto by following the upward flow of the water.

The member 7 is a duplex bowl, duplex because it is provided with an inner wall 8', and an outer wall, and because it provides a plurality of separated passages for the flow of the water. The water passing upward through the nipple G, meets the baffle plate 9 and is forced to take the right passage 10, reaching the top of the passage it is once more turned from its course, this time to the left, it pours into the filter 11.

The lter is constructed of a plurality of perforated plates 12, which have been placed in a pot 13 certain distances apart. The plates are placed one above the other, and I have shown three plates each perforated, though each provided with perforations of different diameters. Beneath each plate I place filtering material and I prefer that it be also of different size, the coarsest on top, a finer next, and a rather fine liltering material on the bottom. In my experiments I have used charcoal as the coarse filter, mineral wool as the intermediate, sharp sand and quartz as the finer filter, although these may be changed or varied.

An outlet 14 in the bottom of the filter 11, coincides with a passage 15 in the inner wall of the member 7, allowing the water, after it passes through the filter, to flow upward through the passage 16 into the globe 17 The globe 17 is of clear glass, and is provided with a plurality of passages or perforations, each surrounded with a properly formed flange for strength, and for supporting a plurality of metallic fixtures which will be described later. l

The globe or dome 17 is cast into a brass fitting 18, and the lowermost passage in the dome coincides with an angle passage 19 through the brass fitting. The fitting 18 is screw-threaded upon its interior and screws down upon the .outside of the member 7 completely closing the top thereof, and allowing for the passage of water only thro-ugh the passage 16 and the perforation 19 in register therewith.

Under ordinary conditions the dome 17 will'be filled with water ready to flow outward to any of the mouth pieces. A nipple 20, flanged kat the outside at 21, and provided, with the soft gasket 22, and the lock-nut 23 at its inner end connects a regulating and controlling valve with each of the passages 24 in the dome 17. There are four of the passages 24 at mid-height of the dome 17 and arranged at the quarterings of the dome.

The regulating valves are of peculiar construction and I will describe them in detail though because of their similarity, a description of one will serve for all.

The valve is a three way valve having the casing 25 provided with the inlet passage 2G, the upwardly disposed outlet passage 27 and the clean-out passage 28, normally closed by means of the cap 29. The valve seat is produced in the inlet passage 26, and the extent of the opening of the valve is controlled by the bulb 30, secured by the locknuts 31 against the stop 32, upon the valvestem 33. A guide member 34 serves to keep the valve-stein in line and serves another function of providing a seat 35 for the pack ing 3G. The guide member 34 is, at 37, screw-threaded into the casing 25 and may when occasion requires be removed together with the valve-stem and bulb, for repacking or other repairs. A spring 38 acting be tween the stop 32 and the guide member 34, holds the bulb normally in position to check the flow of water. The amount to which the bulb will interrupt the flow is regulated by the thumb-nut k40, and the lock-nut 41 screw-threaded upon the valve-stem 33 and -operable into and against the bonnet 42. This bonnet is screw-threaded at 43 to the outside of the valve case 25, and protects from dust and interference, the inner working parts of the valve. A button 44, serves as a convenient means for withdrawing to any limited extent, the bulb away from its seat, thus allowing a more or less full flow of water through the valve, and should a full flow be desired for a great length of time the pin 45 may be engaged in the notch 4G, thus holding the valve-stem withdrawn until the pin is again disengaged.

A short nipple 50 connects the upper out-- let passage of the valve with the mouthpiece and the parts adjacent thereto, and operable therewith.

Y The mouth-piece proper is of glass, and is constructed ofan upwardly extending and centrally perforated nipple 51, which has cast integral therewith a flange or base 52. The mouth-piece is supported in a'metallic cup 53 and between the cup and mouthpiece, a soft rubber packing ygasket is introduced. Y

The metallic cup 53 is screw-threaded on the outside as shown at 55 and a ring or bezel 56 is screwed upon the screw-thread 55. Between the inner' base of the bezel and the rim or the glass mouth-piece, a second rubber gasket 57 is introduced.

The upwardly extending rim of the bezel 5G retains the water in the pocket 58, produced by the peculiar construction and fit of the parts, and I introduce a drain pipe 59 through the bezell to lead away the overflow into the basin 4. It is my Vintention that a certain quantity of water will flow continuously out of the central passage of the mouth-piece or nipple, keeping the nipple free from dust and other foreign and harmful matters, therefore the flow through the pocket 58, and the pipe 59 will be continuous.

The drip from all the drinking nozzles or mouth-pieces will flow into the basin 4 and will lead from there through the waste-pipe 60 into the sewer or any other convenient drain. For sanitary reasons I have introduced a trap G1, into the drain pipe 60, and I have also produced a cleanout passage at or near the bottom of the upward,'left hand passage 16. This cleanout passage is closed by a screw-plug and becomes particularly advantageous should any of the filtering material sift throughthe aperture 15.V

An overflow passage is provided `for the basin and a cap protect-s the overfiow inlet as is shown in dotted lines in Fig. 1.

On the front side of the globe 17, I have shown a fitting somewhat different in construction from those secured to the sides of the globe, the front tting is provided with a. valve but is without the mouthpiece. Y In soV this fitting the upper passage from the valve is closed by a .cap 29, and the lower passage is provided with a nozzle 29.

At mid-height of the pedestal 2, I have arranged to accommodate a step to be used by children or persons who are too short to reach the mouth-piece conveniently.

I cast a plurality of lugs 90 on the eX- terior of the pedestal 2 and provide a plu rality of clips 91, supporting a step 92 and arranged to be detachably secured upon the lugs 90. A handrail 93, supported about the upper edge of the basin 4, by means of the posts 94, and the balls 95 serves as a steadying means for a person standing upon the step 92.

Another added feature of my device is shown in Fig. i' and comprises the cap 100 which may be hingedly connected to a band 101 carried by the nipple 20. I may fit one of these caps to each of the drinking nozzles or I may arrange to have but one or more of the nozzles so covered. The pivot 102, by which the cap is hinged to the band 101 is a shaft and carries at one end a crank 108, and crank pin 1011. A slide 105 is by means of the slot 106, and headed pin or screw 107, secured to the side of the valve casing 25. The outer end 108 of the slide 105 is forked and st-raddles the valve stem 33, heilig' secured thereto between the thumbnut i0 and the lock-nut 41. An elbow 109 and upward projection is formed at the inner end of the slide 105 and is so arranged that when the cap 100 is open, the crank pin 10-11will operate against the elbow and upward extension 109, causing the slide 105 to be moved forward or outward, opening the valve to the required extent and allowing a fiow of water only while the cap is open.

Modifications may be made within the scope of the appended claims without departing from the principle or sacrificing' the advantages of this invention.

In Fig. 5, I have shown a mouth-piece having two upwardly extending nipples and I arrange this mouth-piece in such a manner as to throw a stream toward a common center, this construction has the advantage that the lips do not have to be placed about the nipple as water may be taken from the junction of lthe two streams.

I have shown the filter plates 12 constructed of a peculiar design found in my experiments to be very satisfactory, but it is obvious that simple metallic disks may be used.

The dome 17 may be constructed to accommodate a greater or less number of drink ing nozzles or mouth-pieces and parts adjacent thereto.

Other modifications may be made by a good mechanic.

In Fig. l, I have shown a means for conneet-ing the outlets at the top of the globe by means of a cap 80 screw-threaded upon a fitting 81. A dome 82 is pressed against the outside of the glass so as to give the whole a finished appearance, and a rubber gasket 83 closes the joint between the fitting 81 and the glass making it water tight. In this construction the nipples 20 are replaced by the goose-neck tubes 84. In this construction the glass globe will always re main filled with water even when the pressure is shut off.

I-Iaving carefully and fully described my invention what I claim and desire to secure by Letters Patent is 1. A drinking fountain, having a liquid inlet passage, a filter arranged within said passage, a glass distributing dome arranged upon said filter, and provided with a plurality of outlet passages, each provided with a crystal nipple, said dome performing the double function of a distributing head and display chamber as herein specified.

2. In combination with a drinking fountain having inlet and outlet passages, a crystal display and distributing head arranged between said passages and provided with a plurality of perforations arranged about said display head at mid-height thereof, a plurality of crystal nipples connected to said display head, each said nipple being supported in a metallic cup and retained therein by a screw-threaded bezel and soft rubber packing as herein specified.

3. In combination with a drinking fountain having inlet and outlet passages, of a crystal display and distributing head arranged between said passages, said display head provided with a plurality of passages arranged at mid-height thereof, and a crystal nipple connected to each said passage and a regulating valve between said nipple and said display head as specified.
